EACH BODY 7 HAS A TRANSVERSAL CHUTE 8 WHICH RECEIVES THE TILE HOOKS AND WHICH DEFINES ON THE LOWER FACE OF EACH BODY A STOPPER AGENCY TO ENGAGE ON A SUPPORT LATTIS 2 OF THE ROOF. THESE WATERPROOFING COMPONENTS 1 ALLOW THE LAYING OF TILES OR FLAT SLATES WHICH DO NOT LATERAL INTERCHANGE, WITHOUT HAVE TO STACK THE TILES IN THEIR CENTRAL REGIONS.

Description

_-1 _ The present invention relates to roofs, and more

  particularly the waterproofing of roofs comprising rows of tiles, slates or

  all other individual elements overlapping.

  In such a roof, the tiles or similar elements of the roof are supported by a plurality of spaced battens, fixed transversely to a plurality of sloping rafters of the roof. Conventionally, the front end or head of each tile is provided with a transverse chock on its underside, which engages the front edge of the lath on which the tile rests, in order to prevent the tile from sliding off the roof The trailing edges of the tiles of a given row rest over the heads of the tiles in the adjacent lower row, so that water can descend from one tile to another along the roof without seeping into the underlying area

of the roof.

  However, it is clear that it is essential, in such a roof, that water is prevented from infiltrating between the lateral edges of the adjacent tiles, that is to say through the lateral joints of the roof tiles. a given row For this purpose, many

  of roof tiles are provided with regions to assemble

  complementary and embedding along their lateral edges, and the water seeping between the lateral edges of the tiles is collected by such

  regions, and descends along them.

  However, in many applications, often for aesthetic reasons, as well as in traditional roofs, it is undesirable to use interlocking roof tiles, and so-called flat tiles or slates are preferred instead. , which do not fit together, the -2- side edges of a tile being simply in abutment

  against the edges of the adjacent tiles in the row.

  In such a roof, to prevent water from infiltrating below the roof space, it was necessary to lay the tiles or slates substantially in three thicknesses and staggered, so that the joints between the tiles of any row

  extend above at least one row below

  adjacent, offset from the first However, it is obvious that this complicates the roofing process and requires a greater number of tiles or slates for a given roof area,

  which implies an increase in the cost.

  In an attempt to overcome this drawback, it has been proposed to provide strips of felt for roofs arranged just below each row of tiles, which collect and drain any water infiltrating between the lateral edges in abutment of the tiles. However, this method of roof sealing is somewhat laborious, and further complicates

the hedging process.

  According to a first aspect, the invention relates to a sealing member intended to extend below a row of tiles, slates or similar roofing elements, of a roof, and having the effect of draining water seeping between

  the tiles or elements of said row which represent it

  cover towards the upper surface of tiles or elements of the row situated immediately below, said member having, near its front end and on its lower face, a stop arranged to engage on the front edge of a lattice of

the roof.

  Thus, the sealing members according to the invention can be arranged below each row of tiles of a roof, so-called flat tiles or slates, not arranged to fit along their lateral edges, thus being able to be laid in a conventional way, that is to say so that only the front and rear parts of the tiles overlap The sealing members collect and drain any water infiltrating between the lateral edges of the tiles, thereby preventing the water to enter space

of the roof.

  The sealing member is quick and practical to install, and does not complicate the covering process The member is put in place before the tiles of a given row are laid -, the stop of the member engaging on the anterior edge of the underlying lath so as to position the organ and prevent it from descending by sliding along the roof, the trailing edge of the organ resting on the upper surface of the tiles of the row located immediately above The tiles constituting the next row can then be laid in a normal way, only the sealing member being located directly

below it.

  The stop can be provided in any suitable manner, and can for example be a flange, directed downwards at the anterior end of the member, arranged to effectively hang on the underlying lath of the roof However, in a preferred embodiment, the member comprises a transverse chute near its anterior end, arranged to receive during installation the hooks of the tiles or elements which cover it, and defining on the underside of the member said -4 - stop. In a preferred embodiment, the sealing member has a plurality of recesses arranged to be covered by the lateral edges of the tiles or elements, and defining channels for the flow of water which infiltrates between the edges lateral Thus the water falling on the sealing member is channeled towards the upper surface of the tiles of the row located immediately below, which is conventionally

  offset from the first.

  The invention also relates by extension to a sloping roof including sealing members according to the invention, although the shape of the sealing members may vary. Thus, according to a second aspect, the invention relates to a sloping roof comprising transversely rows of closely adjacent tiles, slates or similar roofing elements, the structure of the elements and the arrangement of the adjacent elements in each row being such that the regions in which such adjacent elements are brought together can provide at least rainwater partial access towards the interior of the roof, the elements of each row overlapping the elements of the row located immediately below by simple superposition, so that, for each of the regions where the adjacent elements of a row are combined, there is a part sealed by the element of the upper row which covers it, a part sealed by the underlying element of the lower row, and a remaining part which can still give rainwater at least partial access to the interior of the roof, characterized in that a plurality of rigid sealing members are provided, each extending below a plurality elements of a row and sealing the remaining parts of said regions where the adjacent elements are joined, the members serving to channel any rainwater passing through such parts towards the upper surface of the elements of the row situated below,

  A preferred embodiment of the in-

  vention is described below, by way of example only, with reference to the accompanying drawings, in which: FIG 1 is a sectional view of a roof including a sealing member according to the invention, FIG 2 is a plan view of a sealing member according to the invention, and FIG. 3 is a sectional view on a scale

  enlarged along line III-III of Fig 2.

  First of all with reference to FIG. 1, a roof is shown comprising rows of overlapping flat tiles or slates 1 for roof, supported by transverse wooden laths 2 which are fixed to the sloping rafters 3 of the roof In a conventional manner , a layer of bituminous felt for roofing 4 is fixed between the battens 2 and the rafters 3, and the trailing ends 5 of the lowest row of tiles end at the edge of the roof, above a gutter 6 Thus l water can descend along the tiled roof, finally reaching the gutter 6, without entering the underlying space of the roof However, the adjacent tiles in each row do not overlap, and the water s infiltrating between the side edges in

  tile stopper can thus access the roof space.

  6 - Despite the fact of providing the layer of felt for

  roof 4, this is completely undesirable.

  To overcome this drawback, sealing members 7 are arranged directly below the tiles of each row. As shown in FIGS. 2 and 3, each member 7 has the shape of an elongated strip in which a transverse chute 8 is formed. near its anterior end, and has a plurality of bevelled recesses 9 regularly spaced in the direction of its length. The strip can be made of any suitable material, for example a plastic material or metal. During the construction of the roof, the members 7 are placed in the direction of the length of a given lath before the tiles of this row are laid. Each member is put in place by engagement between the stop of its lower face, formed by the chute 8, and the lath of the underlying roof, on which the organ rests The trailing edge of each organ rests directly on the upper surfaces of the tiles in the row immediately below L are tiles are then placed over the sealing members so that their hooks 11 engage in the chute

  8 of the associated member.

  The tiles 1 are placed on each member 7 so that their abutment edges or side seals are located above the recesses 9 of the member 7 Thus any water seeping between the side edges of the tiles of a particular row is collected by the members 7 and channeled in a recess 9 towards the upper surface of a tile of the row located immediately below, conventionally offset from -7- the first The water is thus prevented from entering roof space It will be understood that a number of sealing members are provided along each row, and that the lateral edges in abutment of the adjacent members are offset with respect to the lateral edges

  against the tiles that cover them.

  If desired, the tiles 1 can be fixed to the battens 2 by means of nails which can be driven with the help of a hammer through the

  sealing members, in the underlying laths.

  Alternatively, suitable tile ribs can be provided, in which case appropriately spaced openings can be made in each sealing member, through which the ribs extend; if necessary, such openings can be sealed by appropriate means.
